Maunawili Falls Hike
This hiking trail in Kailua is great for hot days because it’s almost entirely covered by trees and foliage. The trail itself follows a creek up the hillside through a lush forest until you arrive at a swimming hole that features a lovely waterfall and a few great jumping-off points for brave cliff jumpers. A few words to the wise: The trail can get muddy when the creek is high, so wear appropriate shoes. It’s also a good idea to pack some bug spray.
